Update at 5:00 p.m. EST Monday:
This blog is no longer live, as the severe threat has ended across the Midwest and the Northeast. Detailed reports of the event can be found below.
Snow and ice spread across the Northeast in the early morning hours Monday as colder air rushed down from the north, meeting up with moisture from the west.
The storm caused major air and traffic disruptions on Monday, as many of the largest hubs in the mid-Atlantic were in or near the path of the storm.
The heaviest snow--with amounts of 6 inches or so--unfolded from the West Virginia mountains to northern and central Virginia to extreme southern New Jersey.
This included Washington, D.C., Harrisonburg, Va., Dover, Del., and Atlantic City, N.J.
The majority of the snow fell during the morning and early afternoon hours on Monday. By Monday evening, a sprawling area of high pressure building in from the west, brought an end to the snow as colder, drier air moved in and the storm moved offshore.
